c86ed71d63
This patch enables float128 support for x86_64 and x86. All GCC versions that can build glibc provide the required support, but since GCC 6 and before don't provide __builtin_nanq / __builtin_nansq, sNaN tests and some tests of NaN payloads need to be disabled with such compilers (this does not affect the generated glibc binaries at all, just the tests). bits/floatn.h declares float128 support to be available for GCC versions that provide the required libgcc support (4.3 for x86_64, 4.4 for i386 GNU/Linux, 4.5 for i386 GNU/Hurd); compilation-only support was present some time before then, but not really useful without the libgcc functions. fenv_private.h needed updating to avoid trying to put _Float128 values in registers. I make no assertion of optimality of the math_opt_barrier / math_force_eval definitions for this case; they are simply intended to be sufficient to work correctly. Tested for x86_64 and x86, with GCC 7 and GCC 6. (Testing for x32 was compilation tests only with build-many-glibcs.py to verify the ABI baseline updates. I have not done any testing for Hurd, although the float128 support is enabled there as for GNU/Linux.) * sysdeps/i386/Implies: Add ieee754/float128. * sysdeps/x86_64/Implies: Likewise. * sysdeps/x86/bits/floatn.h: New file. * sysdeps/x86/float128-abi.h: Likewise. * manual/math.texi (Mathematics): Document support for _Float128 on x86_64 and x86. * sysdeps/i386/fpu/fenv_private.h: Include <bits/floatn.h>. (math_opt_barrier): Do not put _Float128 values in floating-point registers. (math_force_eval): Likewise. [__x86_64__] (SET_RESTORE_ROUNDF128): New macro. * sysdeps/x86/fpu/Makefile [$(subdir) = math] (CPPFLAGS): Append to Makefile variable. * sysdeps/x86/fpu/e_sqrtf128.c: New file. * sysdeps/x86/fpu/sfp-machine.h: Likewise. Based on libgcc. * sysdeps/x86/math-tests.h: New file. * math/libm-test-support.h (XFAIL_FLOAT128_PAYLOAD): New macro. * math/libm-test-getpayload.inc (getpayload_test_data): Use XFAIL_FLOAT128_PAYLOAD. * math/libm-test-setpayload.inc (setpayload_test_data): Likewise. * math/libm-test-totalorder.inc (totalorder_test_data): Likewise. * math/libm-test-totalordermag.inc (totalordermag_test_data): Likewise. * sysdeps/unix/sysv/linux/i386/libc.abilist: Update. * sysdeps/unix/sysv/linux/i386/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/libm.abilist: Likewise. * sysdeps/i386/fpu/libm-test-ulps: Likewise. * sysdeps/i386/i686/fpu/multiarch/libm-test-ulps: Likewise. * sysdeps/x86_64/fpu/libm-test-ulps: Likewise.
